Digraphs. A directed graph (or digraph ) is a set of vertices and a collection of directed edges that each connects an ordered pair of vertices. We say that a directed edge points from the first vertex in the pair and points to the second vertex in the pair. We use the names 0 through V-1 for the vertices in a V-vertex graph.Graph theory is the study of mathematical objects known as graphs, which consist of vertices (or nodes) connected by edges. (In the figure below, the vertices are the numbered circles, and the edges join the vertices.) Any scenario in which one wishes to examine the structure of a network of connected objects is potentially a problem for graph theory. …Examples of Complete graph: There are various examples of complete graphs.
